[Xen-devel] [PATCH v4 1/6] arm/arm64/xen: hypercall.h add includes guards

[Pavel Tatashin <pasha.tatashin@xxxxxxxxxx>]

The arm and arm64 versions of hypercall.h are missing the include
guards. This is needed because C inlines for privcmd_call are going to
be added to the files.

Also fix a comment.
